More on this subject...

I just walked over to Tom's office and talked w/ him about this... X/Open
defines a getsid(), which returns the process group ID of the session
leader of the specified process.  (calling w/ pid == 0 means calling process).

Since the process group id of the session leader is guaranteed to be the
process id of the session leader (see enterpgrp()), I believe Tom's patch
is completely correct.

I would also like to implement getsid(), per XPG 4.2.  More diffs to
follow.
